PHOTOGRAPHIO CAMERA.

Application led February 24, 1925.

My present invention relates to photography and more particularly tophotographic cameras and to those of the folding pocket type in which afolding front and bellows are drawn out from a body upon a bed whichforms a hinged door for the body or are closed within the body beneaththe bedA andy door and the invention has for its object to provide acamera of this type fitted with an improved track and carriage for thefront whereby the latter may be moved with greater facility between thebody and the bed. f

In the drawings:

Figure 1 is a frontV view of a. folding pocket camera provided with afront, carriage and tracks constructed in accordance with andillustrating one embodiment of my invention;

Figure 2 is a fragmentary plan view of the camera bed with the bellowsremoved and taken in horizontal section through the body and frontsubstantially on the line 22 of Figure 1;

Figure 3 is a horizontal sectional view taken through the camera whenfolded subH stantially on the line 3-3 of Figure 1;

Figure i is a section through the camera bed on the line 4 4 of Figure2;

Figure 5 is ay perspective view of one of the tracks within the body.

Similar reference numerals throughout the several views indicate thesame parts.

The type of camera to which this invention relates as before indicatedis the folding pocket type embodying a body l having an opening 2 at thefront normally closed, when the camera is folded, by a hinged door 2fLthat constitutes a bed on which the lens supf ports move when focusingwith the camera extended as 1n Figure 1. The bed is hinged to the bodyat 3 and a bellows t extends from the margin of the opening 2 to thefront 5 supported. on the carriage indicated generally at 6., When thedoor and bed is extended the front is pulled `out upon the bed and whenthe camerais folded the bellows is collapsed and the front and carriageare moved into the recess of the body 1 all as usual in such cameras.

rlhe carriage 6 slides upon continuing tracks one section of which, 7,is located on the floor of the body 1 and the other section of which, 8,is secured to the bed 2. Where these tracks on bed and body are of thesame Serial No. 11,087.

and bed 2 isv closed, YThis results in a break Y or space between thetwowhen the bed is extended which is apttocause 'the carriage to catchor jam in running from one set of tracks to the other.

In the practice of my present invention l so form these tracks that theyform a con tinuous slide for the carriage without. how` ever, being instrict alignmentso that the end of the bed-section can be broughtlaterallyopposite to the end yof the" body track section and move pastit when swung to folded position. To these ends the track sections 7 inthe body are formed (as best shown in Figures 2, 4t and 5) with inwardlyturned flanges constituting inside grooves or ways 9 while the tracksections 8 on the bed 2a constitute outwardly turned flanges which areformed on a plate 10 suitably secured to the bed by rivets 11 on whichthe track 8 slides to a limited extent for focusing purposes. The tracksections of the body are shown secured thereto by rivets 12.

On the bottom of the carriage block 6 is a plate 13 having its sideedges turned downwardly and inwardly to form yokes or beads as indicatedat 14. The rounded flanges thus produced fit slidably in the grooves orlways 9 of the body track sections 7 as shown in Figures 8 and 4. 1Whenthe carriage is drawn out these outer surfaces of thebeads leave theways 9 and the inside hooked portions of the flanges 14; ride upon theoutwardly turned flanges 8 of the bed sections as shown in Figure 1. Inother words the thickness of the en port-ion 14C of the carriage makesa. clearance between the two differently formed track sections one ofwhich engages eXteriorly and the other interiorly. In this way when thebed 2 is folded from the position of Figure 2 to that of Figure 3 thetrack sections 8 thereon Suitable clamping devices are employed forholding the carriage block in any position to which it is adjusted onthe bed but this means is not shown in detail as it forms no part of thepresent invention. lt is sufcient to say that the clamps are released bypinching together the linger pieces shown at 15 by which the carriage ismoved on the bed and which, When released, automatically elect theclamping action.

I claim as my invention: l

l. In a folding camera, the combination with a, body and :i bed hingedthereto? of track sections on the bed and body, respec` tively, focusingdevices for moving the track section on the bed relatively to that onthe body, and a lens carriage slidebly movable from one track section tothe other, the respective sections having;r lateral clearance so thatone set of sections moves between the others when the bed is folded.

2. In a folding camera, the combination with n. body :ind :i bed hingedthereto` of track sections on the bed and body, respectively, focusingdevices for movingP the truck section on the bed relatively to that onthe body and having their proxinmte ends e):w tendine` to the axis ofthe hinge when the bed is extended but oli'set from each other so thatone set of sections moves between the others when the bed is folded, und:1 lens carriage slidzibly movable from one track section to the other.

3. In a folding` Cameri, the combination with u. body and i bed hingedthereto, of track sections on the bed and body. respeew tively, focusingdevices for moving' the tra ck section on the bed relativelyy io that onthe body, those on one part beine` arranged out of alignment with thoseon the other but each being provided with `guides, those on one of themembers being` on the outer sides of the track sect-ions and those onthe other being on the inner sides of the track sections, and a.rei-ringe movable with ,it continuons sliding' movement from one set ofsections to the other, said carriage comprising :i sheet metal yokehaving' n hook formation at each side whereby the terminal of the hookengages one truck and the bend of the hook engages the other track.
